I'll be completely honest and say that I know next to nothing about the ins and outs of 'under the bonnet'.
I love my 2001 330 however it's an auto and is damn expensive to run and I am going to have to get rid of it at a loss, unless I can find someway to improve its thirst.
Is an economy remap worth it on the engine in this model? What could I expect to gain from one? And how much might one cost?
Any advice welcome,
